Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464316, here are decompositions:

47 + 31464269 = 31464316
83 + 31464233 = 31464316
167 + 31464149 = 31464316
173 + 31464143 = 31464316
179 + 31464137 = 31464316
269 + 31464047 = 31464316
353 + 31463963 = 31464316
419 + 31463897 = 31464316

Showing the first eight; more decompositions exist.
